摘要
根据已建矿井水处理工程设计及运行经验,对新建的矿井水处理工程的设计进行了改进。实践表明,改进后的矿井水处理系统的抗冲击负荷能力增强,大大减轻后续工艺的负荷,适应了进水水质变化大的要求,使后续的预处理工艺(包括絮凝沉淀及快滤)及反渗透脱盐工艺的运行更加稳定。矿井水中加入50 mg/L PAC和1 mg/L PAM后,絮凝沉淀效果能满足后续工艺水质要求。预处理后再经反渗透工艺处理,出水的电导率稳定在15~20μS/cm,可直接用于饮用水及配乳液用水。
According to design and operation experience of already built mine water treatment engineering, the design of new mine water treatment project was improved. Practice showed that the shock load capacity of water treatment system was enhanced after the improvement of the mine water engineering. The load of subsequent process was greatly reduced, which was adapted to the influent water quality changes in requirements. The follow-up of the pretreatment process (including the fiocculation precipitation and filtration) and reverse osmosis desalting process run more stable. When 50 mg/L PAC and 1 mg/L PAM were added into mine water, the effect of flocculation and sedimentation could meet the subsequent process requirements. After treated by pretreatment and reverse osmosis process, the water could be directly used for drinking water and water with milk, and the conductivity of it was stable in the range of 15-20 uS/cm. A new water source for the mine production and life was provided alter the mine water treatment project put into operation
